This one is a free but a very popular plugin, which is always kept updated to stay compatible with the latest version of WordPress. The plugin has been launched in a newer version too, which supports translation. This particular version is specifically for English, but you do have an option for another language. It supports 16 different social media platforms and comes with several actions which can be implemented to each of those icons.

Plugin highlights:

It can let you keep the social sharing bar either floating or sticky. It can be a personal choice but I’ll prefer the Sticky one.

It can allow you to showcase the counts of social shares or hide them from the normal visitors.

You can decide the placement of the icons and can totally control it.

The plugin is extremely easy to use and also comes with a documentation to help.
